If you haven’t already, test that you are able to SSH into the server. SFTP uses the Secure Shell (SSH) protocol, so if you are unable to SSH you probably won’t be able to SFTP either.
ssh your_username@hostname_or_ip_address
Start SFTP Session
This uses the same syntax as SSH and opens a session in which you can transfer files.
sftp your_username@hostname_or_ip_address
